Within the human body, there are multiple fantastic electrical systems that keep us alive, well, and thinking. Every time we think a thought, our brain is sending from 5-50 messages per second from the billions of neurons within it. Additionally, we don't often stop to think about how our heart is maintaining a very important rhythm that is executed with constant electrical pulsations. But how is this electrical system created/maintained?

Faraday Generator

There is no definite "origin" of electricity, as it has been observed and experimented with since the time of the Romans. But the first actual electrical system comes from our hero Michael Faraday, who created a small and simple electrical generator. This generator functioned by running a magnet through a coil of wires, which moved the electrons within the wires creating current. While this system was extremely simple, it's principles hold consistent with how all electrical systems still work today.

the heart












Sometimes your heart gets kind of tuckered out, and it starts skipping beats and pulsing wrong, too slow, or too fast. This condition manifests itself in ways that you have might have heard of, such as arrhythmia or bradycardia. Enable to fix this problem, doctors and biomedical engineers developed a device that you have definitely heard of, the pacemaker.
